Is Bane a criminally insane stalker who has fixed on Scarpetta? Or is his paranoid tale true, and it is he who is being spied on, followed and stalked by the actual killer? The only thing Scarpetta knows for certain is that a woman has been tortured and murdered - and that more violent deaths will follow...
